BACKGROUND

1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a handy type vacuum cleaner, in which a handle installed at a main body is rotated and is folded, and the direction and the length of the handle are adjusted according to a user's physical condition or a cleaning environment so that the handle can be conveniently grasped and the vacuum cleaner can be conveniently used according to the cleaning environment.

2. Discussion of Related Art

Vacuum cleaners are cleaning devices in which a suction force is generated by driving a fan embedded in a main body, air containing foreign substances such as dust and the like is absorbed by the suction force and is dust-collected and clean air that is filtered by an embedded filter is discharged again to the outside.

These vacuum cleaners are classified into a canister type vacuum cleaner, an upright type vacuum cleaner, and a handy type vacuum cleaner according to their shapes.

Among them, in the handy type vacuum cleaner, a handle is installed at an outer side of a main body so that a user can easily grasp the handle with his or her hand, and the handle generally includes a rod that is grasped by a user's hand and a support part that fixes one end of the rod to the main body.

In this way, the handy type vacuum cleaner according to the related art in which the handle is fixed to the support part of the main body, is disclosed in Korean Utility-model Registration No. 20-0447957.

Also, a handy type vacuum cleaner including a handle that is combined with a main body and is rotated according to the related art is disclosed in Korean Patent Registration No. 10-0389289.

However, when the handle is fixed to the support part of the main body or is only rotated as mentioned above, the direction and the length of the handle considering a user's physical condition or a cleaning environment cannot be adjusted.

Thus, in the handy type vacuum cleaner according to the related art, the user must extremely twist a body and a wrist during the usage of the handy type vacuum cleaner. Thus, user fatigue increases when the handy type vacuum cleaner is used for a long time.

Also, since the length of the handy type vacuum cleaner according to the related art is fixed, a cleaning range in a state in which the user grasps the handle is small and thus it is very inconvenient to clean the house from cellar to rafter.

While the present invention is shown and described in connection with exemplary embodiments thereof, it will be apparent to those skilled in the art that various modifications can be made without departing from the spirit and scope of the invention.

As illustrated in FIG. 1, a vacuum cleaner 100 according to the present invention includes a main body 110, a first support part 130, a second support part 140, and a handle 150.

The main body 110 includes an upper housing (of which reference numeral is not indicated) and a lower housing (of which reference numeral is not indicated) so as to divide the main body 110 in a vertical direction.

An air inlet (not shown) for absorbing air is installed on a bottom of the main body 110, i.e., on a bottom of the lower housing, and a plurality of adsorption prevention paths (not shown) are formed at the front of the air inlet along a lengthwise direction of the main body 110 from a front end of the main body 110.

Here, a plurality of ribs (not shown) for reinforcement are installed on the bottom of the main body 110, and the plurality of adsorption prevention paths are formed between the plurality of ribs provided on the bottom of the main body 110.

A fan (not shown) that generates a suction force of air and a filter unit (not shown) that filters foreign substances in the air are respectively installed in the main body 110.

The fan and the filter unit are the same as those of a general vacuum cleaner and thus, detailed descriptions thereof will be omitted.

A handle assembly according to the present invention has a structure in which the length of a handle 150 extents and contracts while the handle 150 is pivoted. The handle assembly 120 includes a first support part 130, a second support part 140, and the handle 150.

One end of the first support part 130 is installed at the rear of the main body 110, and a groove 131 in which one end of the handle 150 is inserted, is formed in the other end of the first support part 130.

When a hinge 132 is inserted into the groove 131 so as to penetrate the groove 131 and to be orthogonal to the handle 150 in a state in which one end of the handle 150 is inserted in the groove 131, the handle 150 and the groove 131 are fastened to each other.

Thus, the handle 150 fastened to the groove 131 is pivoted toward the front or rear of the main body 110 based on the hinge 132.

One end of the second support part 140 is fixed to a top surface of the main body 110, and a mounting groove 141 on which the other end of the handle 150 is mounted, is formed in the other end of the second support part 140.

A detachment unit (of which reference numeral is not indicated) that locks or unlocks the handle 150 mounted on the mounting groove 141, is installed at the second support part 140.

The detachment unit includes a stopper 142, a hinge 143, a prop part 145, and a button 144.

The stopper 142 is disposed in the second support part 140, one end of the stopper 142 is pivotably installed by the hinge 143, and a hanging part 142 a having a hook shape is installed at the other end of the stopper 142.

The hanging part 142 a is exposed to the outside of the mounting groove 141 of the second support part 140 and is inserted in a hanging groove 155 a provided in an outer rod 155 of the handle 150 that closely contacts the mounting groove 141 so that the handle 150 can be locked.

The button 144 is exposed to the outside of the second support part 140, is connected to one end of the stopper 142, and unlocks the hanging part 142 a combined with the hanging groove 155 a.

The detachment unit according to the present invention has been described to lock or unlock the handle 150 using the stopper 142 and the button 144. However, aspects of the present invention are not limited thereto, and any detachment unit that may lock or unlock the handle 150 using the second support part 140 may be used.

The prop part 145 supports the rear of one end of the stopper 142 and prevents one end of the stopper 142 from being pushed toward the rear of the main body 110 when a user manipulates the button 144.

The handle 150 includes an inner rod 151 and the outer rod 155.

One end of the inner rod 151 is fastened to the groove 131 of the first support part 130, and a guide hole 152 is formed to penetrate the inner rod 151 in a lengthwise direction of the inner rod 151.

When a guide protrusion 156 of the outer rod 155 that will be described below is inserted in the guide hole 152, the guide protrusion 156 is caught in one end of the guide hole 152 when the user pulls the outer rod 155 combined with an outer side of the inner rod 151. Thus, pulling of the outer rod 155 on the inner rod 151 is limited.

A fixing protrusion 153 is installed at the other end of the inner rod 151 and comes into an inner side of the inner rod 151 as an external force is applied to one side of the fixing protrusion 153, and the fixing protrusion 153 returns to its original state as the external force is removed from the fixing protrusion 153.

When the fixing protrusion 153 is inserted into any one of a first length adjustment hole 158 and a second length adjustment hole 159 of the outer rod 155 that will be described below, the outer rod 155 is fixed onto the inner rod 151.

An inner groove 154 is further provided in the other end of the inner rod 151.

An auxiliary protrusion 157 of the outer rod 155 that will be described below is inserted into the inner groove 154 of the inner rod 151, movement of the outer rod 155 can be minimized in a state in which the outer rod 155 is combined with the inner rod 151.

Also, the outer rod 155 of the handle 150 extends in the lengthwise direction of the inner rod 151, and the guide protrusion 156 is installed at an inner surface of one side of the outer rod 155.

Thus, the guide protrusion 156 is caught in any one end of the guide hole 152 of the inner rod 151 so that pulling of the outer rod 155 on the inner rod 151 is limited.

Also, the first length adjustment hole 158 and the second length adjustment hole 159 are formed in one side of the outer rod 155.

The fixing protrusion 153 of the inner rod 151 is inserted into any one of the first length adjustment hole 158 and the second length adjustment hole 159 so that the outer rod 155 can be fixed onto the inner rod 151.

In the present invention, two of the first length adjustment hole 158 and the second length adjustment hole 159 have been described. However, the number of length adjustment holes is not limited thereto, and when the length of the handle 150 can be further subdivided, more length adjustment holes may be formed.

On the other hand, the auxiliary protrusion 157 is further formed at an inner side of the other end of the outer rod 155. When the auxiliary protrusion 157 is inserted into the inner groove 154 of the inner rod 151, movement of the outer rod 155 can be minimized in a state in which the outer rod 155 is combined with the inner rod 151.

The usage of the vacuum cleaner 100 having the above configuration according to the present invention will now be described in detail.

First, the vacuum cleaner 100 according to the present invention may be used in a state in which the handle 150 between the first support part 130 and the second support part 140 is folded, i.e., is locked.

In the present invention, the hanging part 142 a of the stopper 142 is exposed to the mounting groove 141 of the second support part 140 on which a rear front end of the outer rod 155 is mounted, and the hanging part 142 a of the stopper 142 exposed to the outside of the mounting groove 141 is inserted into the hanging groove 155 a of the outer rod 155 mounted on the mounting groove 141, as illustrated in FIG. 3A.

In this way, as the hanging part 142 a of the stopper 142 is hung in the hanging groove 155 a of the outer rod 155, the outer rod 155 is combined with and is fixed to the second support part 140 so that the handle 150 between the first support part 130 and the second support part 140 can be maintained in a folded state, i.e., in a locked state.

Thus, when the movement range of the main body 110 does not need to be increased, like in the case in which the user cleans the vicinity of a place where the user sits, if the handle 150 between the first support part 130 and the second support part 140 is locked, the user easily grasps the handle 150, and the vacuum cleaner 100 can be conveniently used.

Next, the vacuum cleaner 100 according to the present invention can be used in a state in which the handle 150 between the first support part 130 and the second support part 140 is unfolded, i.e., is unlocked, as illustrated in FIG. 2.

In the present invention, the hanging part 142 a of the stopper 142 provided at the second support part 140 is separated from the hanging groove 155 a of the outer rod 155 due to an operation of the button 144.

That is, as illustrated in FIG. 3B, when the hanging part 142 a of the stopper 142 is separated from the hanging groove 155 a of the outer rod 155 by pressing the button 144, the other end of the outer rod 155 may be unlocked from the mounting groove 141 of the second support part 140 and may be lifted upwardly.

In this case, one end of the inner rod 151 according to the present invention is fastened to the groove 131 of the first support part 130 using the hinge 132, and as the other end of the outer rod 155 is lifted upwardly, the handle 150 can be rotated toward the rear of the main body 110 based on the hinge 132.

Here, when the outer rod 155 is pulled backwardly in a state in which the fixing protrusion 153 inserted into the first length adjustment hole 158 of the outer rod 155 is pressurized, the outer rod 155 moves backwardly on the inner rod 151.

Thus, a state in which the inner rod 151 and the outer rod 155 overlap in the entire section, as illustrated in FIG. 4A, is changed to a state in which the outer rod 155 overlaps only a part of the inner rod 151, as illustrated in FIG. 4B so that the length of the handle 150 can be increased.

Also, since the fixing protrusion 153 of the inner rod 151 is inserted into the second length adjustment hole 159 of the outer rod 155, the outer rod 155 may be fixed to the inner rod 151 in a pulled state.

In this way, when a cleaning range is wide and the movement range of the main body 110 needs to be increased, as illustrated in FIG. 2, the locked state of the handle 150 is released from the second support part 140 so as to adjust the direction and the length of the handle 150 so that the usage range of the vacuum cleaner 100 can be increased and the vacuum cleaner 100 can be conveniently used.

As described above, in the vacuum cleaner 100 according to the present invention, as one end of the handle 150 is pivotably installed at the first support part 130 and the other end of the handle 150 is detachably installed at the second support part 140, the direction and the length of the handle 150 can be adjusted according to a user's physical condition and a cleaning environment so that the handle 150 can be easily grasped, the usage range of the vacuum cleaner 100 can be further increased in a state in which the handle 150 is grasped and the vacuum cleaner 100 can be easily used while relieving user fatigue.

A handle of a vacuum cleaner according to the present invention has one end that is pivotably installed at a first support part and the other end that is detachably installed at a second support part so that the handle can be pivoted and folded between the first support part and the second support part. Thus, the handle can be pivoted and folded according to a user's physical condition or a cleaning environment.

Furthermore, since the direction and the length of the handle can be adjusted, it is easy to grasp the handle so that user fatigue can be relieved, and the length of the handle can be adjusted so that the usage range of the vacuum cleaner can be increased and the vacuum cleaner can be easily used.

It will be apparent to those skilled in the art that various modifications can be made to the above-described exemplary embodiments of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers all such modifications provided they come within the scope of the appended claims and their equivalents.
